Overcut AI Overcut Playbooks Step Actions

Step Actions Reference

This skill covers how to configure steps in workflow.json, including all available action types, their parameters, and workflow/step-level configuration.

Action Types Overview

Two internal actions (agent.internal.cache-repo, agent.internal.index-repo) exist but are not for playbook use.

Step Structure

Every step follows this shape:

{
  "id": "step-id",
  "name": "Human-Readable Name",
  "action": "agent.run",
  "params": { ... },
  "instruction": "Prompt content from .md file",
  "stepMaxDurationMinutes": 30
}

Rules:

• id must match ^[a-zA-Z0-9-]+$ (letters, numbers, hyphens only)
• id must match the corresponding .md prompt filename
• instruction is required for agent.run and agent.session, omitted for infrastructure steps
• stepMaxDurationMinutes (min: 1) limits individual step execution time

When to Use Each Action

agent.run — Single-pass tasks

Use for straightforward tasks where one agent can complete the work:

• Analyzing code and producing a plan
• Reading data and formatting output
• Simple file generation or modification

agent.session — Coordinated execution

Use when a step needs oversight, multi-agent coordination, or iteration:

• Multi-agent delegation: Coordinator assigns chunks of work to sub-agents
• Iterative loops: Draft → review → revise cycles with max iteration limits
• Error recovery: Coordinator detects failures and retries or adjusts
• Verification-heavy tasks: Each sub-task's output must be confirmed before proceeding
• Interactive sessions: User provides feedback during execution (via listenToComments)

See the agent-session-design skill for detailed coordinator patterns.

git.clone — Repository cloning

Clones one or more repositories into the agent workspace:

{
  "id": "git-clone",
  "name": "Clone Repo",
  "action": "git.clone",
  "params": {
    "repoFullName": "{{trigger.repository.fullName}}",
    "branch": "{{trigger.pullRequest.headBranch}}",
    "cloneOptions": {
      "depth": 1,
      "filter": { "type": "blob:none" },
      "singleBranch": true
    }
  },
  "instruction": null
}

repoFullName accepts:

• A literal string: "owner/repo"
• A template expression: "{{trigger.repository.fullName}}" or "{{outputs.identify-repos}}"
• At runtime, can resolve to a string, string array, or object array (from repo.identify)

cloneOptions:

• depth (int): Shallow clone depth (1 = latest commit only)
• filter.type (string): Partial clone filter ("blob:none", "blob:limit=100M")
• singleBranch (bool): Clone only the specified branch
• sparseCheckout (object): { enabled: true, paths: ["src/", "docs/"] }
• ignoreCache (bool): Force fresh clone
• submodules (object): { enabled: true, shallow: true }

repo.identify — Repository identification

Identifies the most relevant repositories for a ticket context (no code access):

{
  "id": "identify-repos",
  "name": "Identify Repositories",
  "action": "repo.identify",
  "params": {
    "maxResults": 3,
    "minConfidence": 0.2
  },
  "instruction": null
}

• maxResults (1-20, default: 1): Maximum repos to return
• minConfidence (0-1, default: 0.2): Minimum confidence threshold
• identificationHints (string, optional): Free text to bias identification

Output: Referenced by downstream steps as {{outputs.identify-repos}}. Typically fed into git.clone's repoFullName.

ci.executeWorkflow — External CI pipeline

Triggers a CI/CD pipeline on an external repository:

{
  "id": "run-tests",
  "name": "Run Test Suite",
  "action": "ci.executeWorkflow",
  "params": {
    "repoFullName": "{{trigger.repository.fullName}}",
    "workflowId": "test-suite.yml",
    "ref": "{{trigger.pullRequest.headBranch}}",
    "inputs": { "test_type": "integration" },
    "waitForCompletion": true
  }
}

• repoFullName (string): Repository identifier with provider inference
• workflowId (string): Workflow filename or pipeline ID
• ref (string, optional): Branch or tag reference
• inputs (Record<string, string>, optional): Key-value workflow inputs
• waitForCompletion (bool, optional): Whether to block until the pipeline finishes

Common Pattern: repo.identify → git.clone

Many issue-triggered workflows need to identify which repos to work with:

{
  "flow": [
    { "from": "", "to": "identify-repos" },
    { "from": "identify-repos", "to": "clone-repo" },
    { "from": "clone-repo", "to": "next-step" }
  ],
  "steps": [
    {
      "id": "identify-repos",
      "action": "repo.identify",
      "params": { "maxResults": 3, "minConfidence": 0.2 }
    },
    {
      "id": "clone-repo",
      "action": "git.clone",
      "params": {
        "repoFullName": "{{outputs.identify-repos}}",
        "cloneOptions": { "depth": 1 }
      }
    }
  ]
}

Workflow-Level Configuration

These fields go in workflow.definition:

Agent Engine

Both agent.run and agent.session support agentEngine:

• "overcut" (default): Full Overcut agent runtime
• "claude": Direct Claude API execution
